SANDING DEVICE FOR AUTOVMOBIL'LESJ Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed February 8, 1905- Serial No. 244,721?- To all whom itmay concern:

Be it known" that'I, AUGUSTUS LEICESTER Moss, a citizenof the UnitedStates, and a resident of Sandusky in the county of Erie and State ofOhio, have invented a new and Improved Sanding Device for Automobiles,of

- 'yvhich the following is a full,'clear, and.exact description.-

The Object of the inventionis to provide a new and improved sandingdevice more especially deslgned for automobiles and similar- J veh clesto prevent the same from slipping while traveling overwet or slipperystreets or roadways.

v The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter andthen pointedout in then aims.

Apractical embodiment of the invention is represented 1n theaccompanying drawings,

forming a part of specification, in which similar character-defreference indicate corresponding parts in all the views. Figure 1 is aplan view of an automobile pro ided with'the improvement, parts beingbrolien out; Fig.'2 isan enlarged sectional side -eleva'tionof the same.Fig. 3 is an enlarg d transverse section of the sand-controlling valve,the section being on theline 3 3 of Fig. 4.3.- Fig. 4 is an enlargedplan view of the same, and Fig. 5 is an enlarged transverse section ofone of the discharge-nozzles.

The sanding deviceu's mounted on a suitable part ofian automobile:A,1and the sand to be scattered over .the' roadway in front of thedrive-wheels A of the automobile is held in a sand-container B,preferably in the form of a hopper con nectedat its lower end with avalve C, having an outletsD, from which branch sand-pipes E in oppositedirections, each pipe being provided at its outer terminal with a flat'nfozz-le orspreader F for spreading the sand in a thin fan-like streamover the roadwayinfront of and around. the drive-wheels, A, sothatthelatter take a firm grip to pre-" vent the automobile from slipping,especially when traveling over wet asphalted streets or similarroadways. The valve 0 is also adapted to connect by a pipe G with acompressed-air reservoir H, into --which air is discharged by theoutlet-pipe I. of an air-pump I of any approved constructiowand actuatedby an eccentric 1 or similar mechanism, adapted to be connected by aclutch J with the driven axle A or otherdriven part of the automobile.

"The valve Q is provided with a valve-casing C, (see Fig. 3,) containingavalve-plug-C formed in its topwith a conical recess a, into the top ofwhich'open portsh'adapted to register with similar ports 0, formed inacap (J held on thecasing C, on which rests thelower end of thesand-container B. The lower end of the recess a terminates in a sidewiseextension a, opening into the outlet-pipe D, and into the said extensiona/opens a nozzle d, contained or [formed in the plug (J and adapted toregister with the pipe G, leading the valve-plug is in a closedposition, so that the ports I) are disconnected from the ports 0, theextension a is out of register withthe pipe D, and the nozzle (2 is outof register with the pipe Gr.

When it is desired to make use of the sanding device, the plug C isturned so as to bring.

the several parts in register, as illustrated in i Fig. 3, to allow thesand to flow from the container B to the registering ports 0 and 6, intothe recess a and to the extension a thereof, in which the sand isengaged by a blast of to the compressed-air reservoir H. Normally airfrom the nozzle d, so that the sand is forced through the pipeD andsand-pipes E into and through the nozzles F, whereby the sand isscattered over the roadway in front of and around. the wheels A for thelatter to take a firm grip, thus preventing slipping of the wheels. i 4

In order to actuate the v'alve-plug'C by-the chauffeur-or other party incharge of the automobile, the followingdevice is provided: On

the lower end of the valve-plug C is secured an arm K,carrying at itsfree end a pin K, extending into an elongated slot L, formed in a rod L,extending lengthwise under the automobile, the forward end of the rod Lbeing connected with a lever "N, having a foot piece N and.

adaptedto be pushed forward by the chauffeurto impart a swinging motionto the lever 3 N and a rearward motion to the rod L. A pring O isconnected with the lever N to normally hold the foot-piece N in arearmost po-.

sition. The rod L also controls the clutch J for connecting ordisconnecting the eccentric I with and from the axle A, and forthispurpose the rear end of the rod L is provided wlth a pin L engaging onearm of a bell-crank lev'er P, having its other arm in the shape of ashifting-fork engaging the clutch J. (See Fig. 1.) spring Q, somewhatWeakerthan tlie sprihg' O, is connected with the bell-crank lever P, soas to hold the same in engagement with the pin L and when the rod L ismoved IIO , bell-crank lever P to shift the clutch J in en r earwardlyon the forward pushing of the foot-piece N then the spring Q acts on thegagement with the eccentric I? to start the pump I with a view to pumpair-into the reservoir H. When the rod L moves rearwardly, the pump isstarted 'ahead of the turning of the valve-plug (J from a non-activeinto an active position, owing to the fact that the pin K travels in theelongated slot L. until the forward end of the slot is reached, and thena further rearward movement of the rod L causes a swinging of the arm Kto turn the valve-plug C from the non-active or closed position to openposition, as illustrated in Fig. 3. When this takes place, sand isforced by the air-blast onto the roadway in front of and around thewheels A, as above described.

By the arrangement described the operator: on pressing the foot-piece N'a short distance forward-that is, until the pin K reaches the forwardend of the slot L' starts the pump I to fill the reservoir H with apredetermined pressure, governed by asafety-v-alve H on theair-reservoir H. Thus the operator can charge the air-reservoir H at anytime while the automobile is running without setting the sanding devicein action. It is, however, expressly understood that when the operatorpushes the foot-piece N forwardly to its full extent then the pump I isstarted ahead of the sanding device to maintain the pressurein-theireservoir H during the time the sanding device is used, so thatat a critical time the sanding device does not fail to act by theabsence of a proper air-blast to force the sand out of the nozzles.

After the slippery place has been passed the operator simply releasesthe pressure on the foot-piece N, so that the lever N and rod L returnto theirnormal positions by the action of the spring 0, the rod L actingon the bellcrank lever P to move the clutch .T out of engagement withthe eccentric 1 and the rod L also causes a return of the plug C back toits normal non-active position to cut offthe airblast and to cut off thesand-container from the pipe D;

It is understood that it is very important that a proper air-blast ishad to positively force the sand onto the roadway, as described, and inorder to produce the desired-result the pump is started ahead of theturning of the valve-plug C to accomplish the desired result.

The device is very simple and durable in construction, is composed ofcomparatively few parts, and is not liable to easily get out of order.

Having thus described my invention, I claim as new and desire-to secureby Letters Patent 1.
